Patented June 24, 1930 UrulTlaDk STATES PATENT OFFICE y CHARLES WALES, l OF LA GRANGE, ILLINOS, ASSIGNOR TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION F NEW YORK APPARATUS FOR ASSEMBLING AND TREATING- ARTICLES Application led December 16, 1926.

This invention relates to apparatus for assembling and treating articles, and more particularly to an apparatus for assembling incandescent lamps. f

A type of incandescent lamp, for instance, a telephone switchboard lamp may comprise a sealed glass bulb' having a pair of electrical contacts in the form of metallic plates fixed at one end thereof to diametrically opposite points of the bulb and contacting with leading in wires connected to a filament mounted inthe bulb, the Opposite ends of the contacts being imbedded in a base composed of insulating material; It 1i has been the practice heretofore in some instances to attach the contacts, previously assembled with their associated base, to the bulb by a4 handmethodwhich has proved costly and which has not resulted in a uni- Jfi formly assembled product las the accurate assembly depended entirely upon vthe skill of the operator.l f I VThe object'of thisjinv'ention is to provide an apparatus for automatically assembling and treating articles, .particularly incandescent lamp parts, expeditiously, accurately and securely with a minimum ofcost.

In `accordance with the general features of this invention as applied to lanapparatus im for automatically assembling 'the previously assembled contacts and bases vwith a sealed evacuated` glass bulb of a telephone switch- Vboard lamp, a plurality of bulbsV are ad-` y vanced due to the intermittent operation of Tiff' va carrierto a position where predetermined amounts of an adhesive material, such as glueare applied at'diametri'cally Voppositel points to each of two adjacent bulbs. While inV a sueceeding'position mechanism includ- 4@ ing a lplurality ofadjustable lingers become' effectivevfor separating the contact springs of' a corresponding number Aof assembled contacts and bases sufii'ciently'to allow them tol be assembled on the bulbs over the' ap- `plied adhesive, this assembly bellg'eiected Serial No. 155,148.

by moving the contacts downwardly over the bulbs. After this operation the contacts are subjected to pressure in such a manner as to press them firmly on the vbulbs and to adjust them in predetermined relation thereto. To prevent possible displacement of the contacts the carrier and the assembled bulbs and contacts pass directly from the assembly positions to an oven wherein they remain until the adhesive has completely dried, after which the assembled articles are automatically ejected.

Other objectsand advantages of this invention will more fully appear from the following detailed description taken in oonneotion with the accompanying drawings illustrating one embodiment thereof, in-

Y AReferring to the drawings wherein like reference numerals; designivte llike Vparts throughout the several figures and nioie particularly to Figs. l1 `to5,v inclusive, of the Adrawings,the assembling apparatus and an .associated oven 37 Vis shown Aas wmounted upon a base orwframe equipped Vwith supporting standardathe lower ends of which are shown fragmentarily to conserve space. Upon the underside of the frame 45 is a motor 46 (Fig. 2) which drives a horizontally disposed revolvable shaft 47 journaled upon a frame'48 mounted upon the upper face of the frame 45 (Figs. 3, 4 and 5), through a belt drive 49. rIhe shaft 47 car- Yries a worm 52 meshing with a worm wheel 58 (Fig. 5) rotatably mounted upon a horizontally disposed shaft 54 journaled on the framev 45. Splined tothelright `endof the shaft 54 (Fig.' 3) is a driven jaw clutch member 55 adapted to be moved into and out of engagement with a driving clutch surface 56 providedon the worm wheel 53 by a pivotal hand lever 597 a bi-f-urcated endV thereof being Yprovided with diametrically opposed pins 60 which project into an annular channel 61 formed in the driven Y clutch member 55. The lever 59 is arranged n to be -1retained ineither itsjinoperative or 1 operative vpositions by A,a latch mechanism v62,.the ,lever .being shown in thedra-wings in its operated position, consequently the .clutch members 55 and 56 are engaged. @Secured to the rotary shaft 54 within the iframe v48is vaplurality of ycam wheels 63, v.6l4fand 65 igs. 13, 5 and 24),;the purpose .ofiwhichfwill-be referred to shortly hereinafter.

formed therein and adapted to press against the periphery of the bulb. Also provided on the container are a pair ofy oppositely disposed slots 79, the .purpose of which will be made apparent as this description progresses. The endless'carrier 30 or sprocket chain is guided throughout itstravel by a plurality of suitably journaled sprocket wheels 84 and in addition at various vpoints between the sprocket wheels the carrier is supported by and slides upon rail members 87. The carrier 30 in its passage through the oven 37 travels a circuitouspath and the means for supporting and guiding it therein and an auxiliary propelling means- 88 therefor, illustrated in Fig. 16,will bedescribed in connection with the `description of the oven to be givenhereinafter.

Mechanism for positioning the bulbs ,at the botto/m of the containers Y Referring to Fig.' 1, as ther intermittently operated carrier 30 with the bulbs 81v moves in the direction indicated by the arrows and just before it comes to the point where a'dhesive is applied to the bulbs, the bulbs are moved under a gravity actuated mea-ns 31 comprising a presser wheel preferably provided with arubber surfaced periphery and rotatably mounted upon an arm 89 pivoted to the rail member 87. The weight of the wheel is just suiicient to move the' bulbs down to the bottom of the containers against the resistance-offered by the springs 82 (Fig. 18) associated therewith in case they are not so positioned bythe attendant during the loading operation.

A cZ/tesioe cantonner Carried upon the upper surface of the frame 45 is a circular container 90 for holding a supply of hot liquid glue or other suitable adhesive composition for use in attaching to diametrically opposite point-sy of lhe bulbs 81 a pair ofc'ontacts 91 assembled upon a base member 94 having insulating properties, suoli as wood (Fig. 22). The liquid adhesive in the container, vthe level of which is indicated by a dotted line 95 (Figs. 4 and 5) is preferably heated by an electrical heating element (not shown). An agitator comprising a pair of blades 90 position-ed adjacent the inner bottom surface of the container 90 and attached to rotatable shaft 97 axially mounted in the circular container 90 maintains the ladhesive' in aconstant state of motion, the shaft 97 receiving motion from a shaft 98 through a pair of cooperating bevel gears 99-99 (Figs. 8, 4 and 5), Vthe shaft 98 rbeing driven `from the Suitable means is connected to the container 90 as indicated by the numerals k100y (Fig. 3) for condensing the steam arising from the' hot liquid glue and returning vrit to the'container for the purpose of maintaining a uniform' consistency ofV the glue. This meansfhas not been disclosed, sinceit is not necessary to a complete;understanding of the present linvention.

- Operating f rams Cperatively associated with the cams 08, 64 and 65l are levers 103, 104 and 105, respectively, the levers 108 and 105 each com )rising a pair of spacedmembers rigidly fixed together, the vlevers being pivoted upon va common shaft`106 journaled in opposite side walls of the frame 48. Rollers 107 carried by the short arms of the levers 103,104 and are arranged to engage and rollupon the peripheral faces of the rotary cams 08, 64 and 65 (Figs. 3, 5 and 24). Referring particularly to Fig. 24 it will be observed thaty the frame 48. It will be apparent that during a complete rotation of the cam wheel 64, from the position illustrated, the interconnected levers will positively be rocked first in a clockwise direction and thence counterclockwise about their pivots 100, therebyv causing the ram 114 to be reciprocated with a uniform upward and downward motion. To prevent the ram` 114 from moving except as acted upon by the cam 64 a spring actuated friction shoe 109 (Figs. 4 and 24) is provided. The shoe 109 may comprise any suitable'material retained in frictional en gagement with the front face of the ram 114 within a slot formed in the frame 48 bya pair of'compressionsprings surrounding a pair of screws threaded into the frame, Reciprocally mounted. in vertical guide lways (Figs. 9 to 12, inclusive) provided in the frame 48 and. centered with respect to the path taken by the containers-80 which lhold the bulbs 81 are a plurality of'rains 113, 114 and 115 operatively connected at. suitable points vintermediate their ends to the levers 108, 104r and 105, respectively, as vindicated in Figs. 5 and 24 wherein the levers 104 and icc 105 are shown in full and dotted lines, re- Y y 65, the shape of their associated leversya'nd 7 the point of engagement of the bifurcatedk ends of the latter-with their jrespective'rams are such that the rams in their vertical reciprocationcause the operation of ay plurality of associated mechanisms, to be described shortly hereinafter, "in, a predetermined timed relation. lThe rams in the operation vspring is necessary in the case of the levers 104, as will be apparent from the description hereinbefore given.

Adhesive convey/071 Attached to the upper end of the ram 114 is an arm 119 (Figs. 3, 4 and 9) which extends forward and -to the right as viewed in Fig. 3 to a point in front of the ram 115. The free end of the arm 119 engages within a notch 120 provided'in a vertically reciprocable link arm 121 disposed in front of the ram 114 and carrying at its lower end an adhesive conveyor 122 normally Vimmersed below the level of the adhesive stored in the container 90. The arm 121 is guided at its lower end by the walls of an Vaperture formed in a cover 123 provided for the container, while other 'guides 124 (Figs. 5 and 9) carried upon the frame 48 serve to guide it at other points thereof in its reciprocation. The conveyor 122 in its reciprocation is operatively associated with an adhesive applying mechanism 32 which will now bedescrib'ed.

Adhesive applying mechanismeV Referring particularly to Figs. 9 and 10 the ram intermediate its ends carries a cross bar 127 which extends through a slot provided in the ram and an equal distance y from opposite sides thereof. Pivotally attached to the ends of the arm 127 and upon opposite sides thereof is a pair of depending levers 128V. Mounted upon the levers 128 are rollers 129 which engage opposite faces 130 provided upon a pair of stationary plates 131, the faces 130 being'providedwith cam portions 132 at their upper ends. The rollers 129 are held in engagement with the faces 130 by a tension spring 134, opposite ends of which are secured to each pair of oppositely disposed levers 128. Attached to the lower ends of each of the levers 128 is a depending adhesive applying nger 135, which as clearly indicated in Fig. 9 Vis normally spaced from vopposite sides of the bulb 81, the inner surface of the linger being concave as indicated by the numeral 136 (Figs. 19 and 20) to lit the peripheral face of the bulb 81. Each of thefingers is integral with and depends from a ring-shaped portion 137 of an angular shaped member 138, the top edge of the Afinger terminating in line -with the lower inner edge ofk the opening in the ring portion 137 for a purpose which will be referred to shortly hereinafter. The angular shaped memberY 138 is adjustable toward and from the bulb 81 by means/of a screw threaded rod 141 journaled ina pair Vof Vupwardly extending-'lugs 142 formed 3 upon the member 138, the Vrod Yhaving a threaded engagement with the right hand lug 142 (Fig. 19). V The rod 141 at one end is rotatably attached to a depending arm of a member 143 which is rigidly iixed tothe lever 128,the opposite yend of the member 143 being provided with a horizontal shelf portion 144, a nut 145 fixed to the rod 141 bearing thereon and forming a lock for retaining the associated linger 135 in a predetermined normal spaced relation from the bulb 81 after rotating the rod 141 by means of a crank portion 146. In the operation of the apparatus while the adhesive conveyor 122 is moving upwardly the lingers 135 are moving downwardly, the fingers dipping into the conveyor at a-point within the container 90 justrbelow the cover 123 thereof, as shown in Fig. 10, thereafter the ngers 135 are raised to the dotted line position, Fig. 9, the conveyor 122 returning to the position thereof also shown in Fig. 9. Upon the fingers 135 reaching substantially the limit of their upward movement they are abruptly moved inwardly toward the periphery of the pair of bulbs 81, (dotted lines Fig. 9) without any appreciable pressure upon the bulbs, thereby applying adhesive-thereto, the latter movement caused by the rollers 129 dropping into 'the cam portions 132 formed upon the plates 131, which movement is assisted by the spring 134. Due to the fingers 135 terminating at their upper ends with the inner circumferential faces of the ring portions 137 it will be apparent that a predetermined quantity of the adhesive will be applied to a predetermined height upon the bulbs 81.

Magazine for supporting base assembles Y A plurality of lamp base assemblies each parallel spaced vertical walls vand 151 f (Figs. 4 and 21), the base assemblies being freely slidable thereon with the contacts straddling theupper edge of the magazine. Y The wall 150 is provided with a depending handle 152 intermediate its length, while` the wall 151 is provided with a lip 153 similarry disposed, which facilitates the mounting of the magazines 149 upon vertical plates 156, one upon each side of the frameV i Y 48, fixed to bars 157 mounted upon the frame 45, the plate 15G-being entered between the g walls 150 and 151 of the magazine with the lips 153 projecting through an aperturer158 provided ina rig-ht angle extension of the plate 156.l It will be apparent that the lip s 153 will serve to guide the plate 156 into the space between the walls 150 and 151 of the magazine 149 and upon being mounted in correct position thereon will prevent its longitudinal displacement during the removal of the .base assemblies therefrom in the operation of the apparatus.` In valignment with the upper horizontal edge of each of the magazines 149 at their inner ends and abutting the inner vertical facesV of the plates 156 at one end with their inner or opposite ends having a 4sliding clearance with the opposite vertical sides of an enlargement 159 provided upon the lower end of the ram 114 are stationary rails 160 (Figs. 6 and S). At their outer ends the rails 160 are similar' in vertical cross-section t0 the vertical plates 156 but gradually become greater in thickness toward their inner ends adjacent the enlargement 159 ofthe ram 114, thus causing the contacts 91 to gradually be spread further apart at their lower ends, as the base assemblies are successively fed therealong into operative position with respect to the ram 114, for a purpose lwhich will be apparent as this description progresses. Formed in the lower end face of the enlargement 159y at either side thereof are notches or depressions 161 (Figs. 6 and 8), the upper end walls of which are V- shaped to substantially conform to the contour of the upper ,ends of the base members 94 as indicated at 164 (Fig. 5). Upon the ram 114 reaching the uppermost point of its travel wherein the upper` end walls of the depressions 161 are sufficiently above the upper V-shaped ends 164 of the base members 94, the base assemblies are moved from opposite directions upon the rails 160, the inner end base assemblies upon each side of the ram being moved into the depressions 161 by the following mechanism.:

Carried upon the frame 45 and arranged in pairs at opposite sides of the yframe 48 are four wind driven pistons 165 (F1g..2) disposed to operate in a longitudinal direction land carrying at their inner ends spring controlled fingers 166 arranged to engage the outer base member 494 of thetrainof base assemblies carried Aupon the magazines 149. The pistons 165 comprising each pair are arranged vertically, one directly above the other with the lingers 166 carried 'at their inner ends mounted on Acarriages 167 (Fig. adapted to slide upon rails 168. For controlling the fingere166, associated with each piston 165, the finger being reciprocally mounted in the carriage 167, there v is provided a bell crank lever 171 fulcrumed upon the carriage with one arm thereof pivoted to the finger 166'and its Vopposite end associated with a leaf spring 172 which normally acts to rock the lever counterclockwise to maintainthe finger 166 in operative position with thebase member 94,

as clearly indicated in Fig. 3. When it is desired to retract the linger 166, which is necessary at intervals in the operation of continuously assembling the lamps, as will be described hereinafter, the operator grasps a handle 17 3. provided upon the carriage 167 and rocks-the lever 171 against it and upon release thereof the linger moves back to its normal position. Only one of the lingers 166 of each pair thereof disposed upon opposite sides of the ram 114 is normally in engagement with the outer base member 94 of the associated train of base assemblies, but they are so arranged upon their respective carriage 167 and rail- 168 that either' one maybe so positioned without interference from the other. Each ofthe pistons 165 is actuated by compressed air supplied from a suitable supply source and directed into the outer end of a cylinder 174 (Figs. 1 and 2) and against the corresponding end of the piston 165 carried therein,:the opposite end as hereinbefore described carrying the linger 166. The air admitted to each pair of cylinders upon either side of the ram 114 is controlled by a four-way valve 175 which is manually operated by a handle 176 (Figs. land 2) supported upon the front of the frame 45, within easy access of the attendant. mannerupon operation thereof and suitable associated pipingtransfers the air pressure from one cylinder to the other. In the op? eration of the apparatus one of the fingers 166 ,of each pair thereof intermittently pushes the train of base assemblies carried upon the associated'magazines 149 therealong and onto the abutting rails 160 and into operative position within the-depres sions 161 of the ram 114. ready to be moved downwardlyrby the ram. .Upon the fingers reaching a point indicated bythe numeral 179 (Fig. 4) wherein all the base assemblies have been moved ,fromV the magazine onto the rail 160, suiiicientspace is left for the removal of the empty magazine without disturbing the continuous feeding operation and the mounting of a filled magazine in its place in the manner hereinbefore described. The attendant thereupon grasps the handle 173 associated with the idleiinger 166 carried by the free piston 165 and engages the The four-way `,valve in a well known C" linger with the outer base member 94 of the train carriedA upon the magazine just mounted, the inner base member abutting theoperative finger 166. Thereafter upon completion of la feeding movement of the operative finger 166 or during the interval in which the base assemblies are not moving along the rail the attendant with one hand retracts the finger 166 Afrom between y theadjacent base assemblies and simultaneously therewith operates the handle 176 of the associated yfour-way valve which transfers the air pressure from the operative van piston to the, idle piston 165 which thereupon continues the feeding operation, the previously operative piston now idle being freely movable back to a position where the finger 1.66 carried thereby is adjacent the inner end ofthe cylinder 174 (Fig. 2). Thus in the operation of. the apparatus the fingers 166 comprising each pair thereof upon opposite sides of the ram 114 are alternately used to provide a continuous feed of the base. assemblies toward the depressions 161 of the ram 114, a pair thereof passing thereinto during` each reciprocation of the rain. for transfer to the pair of bulbs previously treated with adhesiveand positioned. immediately therebelow, as hereinbefore described, by a, mechanism 34. i

Mechanism for spread/ag the Contact; of the base assemblies and transferring them to the' prepared bulbs Pivotally attached at their upper endsto opposite ends of. a cross bar. fixed within a slot provided in the ram 114 intermediate its ends Vand extending an equal distance fromv opposite sides thereof (Figs. 11 and 12) are depending cam levers 181. Y The lower end of each of the levers 181 is bifurcated andl fulcrumed to a centrally disposed bar of a rocking frame 182 (Fig. 12)n intermediate its length and providing lever arms unequal in length. Pivotally attached at its j lower endr tothe outer or long arm of the fit,

frame 182 is a rod 188 having its upper end freely passing through an aperture provided at the top of the frame 48, a nut 18,6 screw threaded onto the end thereof above the surface through which it extends limits the downward movement thereof. Although the mounting of the upper end of only one of the rods '183 is shown (Fig. 4), the other rod is mounted in substantially the same manner. Surrounding the rod`183 intermediate its length is ra coiled compression spring 187, the spring at one end resting against an adjustable collar 188 carried by the rod and its opposite-end against the lower end of a sleeve 189 free upon the rod, the spring normally tending to move the rod downwardly. Formed in each of the levers 181 is an elongated slot 190 provided atk its lower end with an offset` cam portion 198. Stationary pins 194 fixed to the frame 48 extend through the slots which in the reciprocation of the ram 114, to be described hereinafter, causes each of the levers to be rocked alternately in opposite directions about their pivots. V Carried upon each of the frames 182 is a pair of wire lingers 195 (Fig. 7) whichextend in a direction at right angles to the movement of the carrier, each being centered with a base assembly, as previously described, mounted in the depressions 161 ofjtheram 114. The inner ends of i the fingers are providedwith a substantially right angle extension 196 extending upwardly, which in the operation of the apparatus is hooped under the extreme lower ends of the contacts 91 as shown in dotted outline in. Fig. 11. The outer ends of the fingers are associated with an adjustable screw 197 in such a manner that the hooked ends of the fingers may be laterally adj usted, with respect tothe longitudinal center line of the carrier 30 by merely 'rotating the screw, the lingers adjacent their inner ends being .reciprocally mounted and guided in apertures provided-in the frame 182. As clearly shown in Fig. 22 the contact plates 91 of the base assemblies, when not mounted upon the magazine 149 or. rail 160, due to the normal spring pressure therein move into engagement with each other at their lower ends. The purpose of the greater thickness of the rails 160 toward their inner ends will now be described. As the base assemblies are fed along the rails toward the depressions 161 of the ram 114, the contact plates 91 will be spread apart from the position shown in Fig. 22, due to the shape ofthe rails, and further than that shown in Fig. 21 until they are substantially parallel for the purpose of providing suiiicient space therebetween for the insertion of a pair of oppositely'moving plungers, to be presently described, which retain the plates in a parallel relation untilthey are engaged at their lower ends by the hookedr ends 196 of the fingers 195 which are moved simultaneously upwardly and inwardly to hook thereunder during the downward movement of the ram" 114, as will be shortly described.

At` the same instant that the base assemblies are entered in the depressions 161 and simultaneously withy the movement of the ram 114 downwardly, a pair of horizontally reciprocable plungers 198 (Figs. 6, 8 and 11) are moved from opposite directions intothe space thus formed between the contact plates andtherebvy maintaining the contacts lin a substantially parallel position as clearly shown in Fig. 11. The means for operating the plungers 198 in timed relation to the downward movement of the ram 114 and the insertion of the base assemblies in the depressions 161 comprises the following: Referringparticularly to Fig. 8, upon the lower end'of the rotating shaft 67 is fixed .a cam wheel 200 adapted to rock a bell crank lever 201 about its pivot 202 which is disposed,

equi-distant the ends ofr a short arm of the lever, a long arm'thereof engaging the periphery of the cam wheel 200. A tension spring 203 attached at opposite ends to the.

long arm of the lever 201 and to a stationary bracket forming a support for the lever ends thereof being similarly secured to the outer ends of a pair of slide plates 206, the inner ends of the latter carrying the plungers 198. The upper face of the plates 206 slide along the bottom of the rails 160, while the opposite face thereof rests upon a st'ationary guiding and supporting plate 207 (Fig 6). llhe inner opposite ends of the rails 160 are provided with slideways 209 for guiding the plungers 198 in their'reciprocation, (Fig. 6), the plungers being connected to the slide plates 206 by intermediate connecting members 210 secured to the upper surfaces of the plates. rlhus in the operation of the apparatus the cam wheel 20() will be rotated and through the associated lever 201 and the other cooperating members the plungers 198 in timed relation to the other elements of the apparatus will be moved into the V-shaped spaces 199 formed between the contact plates 91 of the lamp assemblies and thereafter withdrawn.

In the movement of the ram 114 upwardly the iigers 195 are moved from the position shown in Fig. 12 to the full line position thereof shown in Fig. 11. Just before reaching the latter position a pair of verti' cally reciprocable plungers 211 carried in slideways provided in opposite rends of the enlargement 159 ofthe ram 114 are caused to move downwardly, in timed relation with the upward movement of the fingers 195, a predetermined distance by the following mechanism: Fixed to the shaft 66 (Figs. 8 and 4) is a cam wheel 212 and engaging the cam face thereof is a roller 214 carried upon one end of a lever 215 secured to a shaft 216 journaled upon the frame 48. Upon the forward end of the shaft 216: is secured a pair of levers 217, `the free'ends thereof directed towardthe ram 114 and upon the front and rear .side thereof, as shown in Fig. 3: Depending from the free ends of the levers 217 are rods 218 supporting upon their lower ends the previously mentioned plungeis 211. A tension spring 221 having opposite ends thereof secured to the forward lever 217 and the frame 48 serves to maintain the roller 214 in contact with'the cam wheel 212. During the downward movement of the plungers 211 they engage ythe upper surfaceof theupwardly moving frames 182 adjacent their inner ends and at a predetermined distance below the lower ends of the contact plates 91 of the base assemblies and thereafter move upwardly along with and in contact with the frames 182 until thehoolted endsA 196 of the lingers 195 aie about to engage the loiver ends of theplates when they are suddenly moved upwardly and away from the frames 182, thereupon the compression of the' springs 187 serves to roclr the outer ends of the frames 182 downwardly,l thereby moving the inner ends thereof quickly upwardly,

the frames pivoting upon the levers' 181. This upward movement of the inner ends of the frames 182 occurs at substantially the saine instant that the oset portion 19B of the slot 190 provided in each of the levers 181 engages the stationary pin v194 which it will be apparent Causes the levers to be rocked toward each other about their pivots upon the cross bar 180 and consequently carrying the fingers195 toward each other simultaneously with the upward movement of the inner ends thereof and thereby hooliingthe right angle extensions 196 thereof under the. lower ends ofthe Contact plates 91, as shown in dotted lines in Fig. 11. lmmediately upon the completion of the latter movement of the lingers 195 the rain 114 starts to move downwardly, the offset portions 193 of the slots 19() formed in the levers 181 instantaneously moving l, away from the pins 194 and causing the levers 181 to be rocked outwardly, thereby flexing the contact plates 91 to the position shown in dotted lines in Fig. 11, the continued movement downwardly of the rain slipping the contact plates 91 down over the previously treated and positioned bulbs as clearly shown in Fig. 12, the ram114 being at its lowermost position. As clearly shown in the dotted line position of the contact plates 91 and the fingers 195, the plates during their. downward. movement are spread such a distance that they will not engage the bulb 81 or the adhesive patches applied thereto vuntil' the fingers release their hold thereon. Upon the ram 114 reaching its lowermost position the lower ends of the, plates abut theupper surface of thecontainers the ends ofthe fingers 195 mov.-

ing into the slots'7 9 formed'in the containers H 80 hereinbefore described and alsov into slots l 224 formed in vertical members225 forming a housing uponv opposite sides yof the carrier 30, the depth of the'slots 7 9 and 224 and the movement of the ngers being such that the latter are withdrawn from engagement with the plates 91 and assume the position shown in Fig. 12. Fixed to one of twolpair of depending levers 226, the purpose of whichv will shortly be made apparent, is a yolre member 227 provided with depending arms 228 uponeach side thereof, the lower ends of th-e arms having right angle portions 229 which, as clearly shown in Figs. 11 and 12, extend toward the carrier 30 and lie very close to the base assemblies positioned in the depressions 161 formed in opposite sides of the enlargement 159 of the ram 114. The portions 229 of theyoke member 227 serve as guards during the transfer of the base assemblies from the position thereof shown in Fig. 11 to that shown in Fig. 12 to prevent tlie base assemblies from falling sideways as viewed in Fig. 6 during their transfer. f v

Mechanism for pressing tlm Contact.; against ille lmll) Pivotally supported upon each of the stationary pins 194 is the pair of depending levers 226 (Figs. 4 and 13) of a mechanism 35 providedv to press the contacts 91 against the bulb and which are aligned as viewed in Fig. 4 with the verticalv center' of the pair of bulb containers 80 to the left of the containers holding the bulbs which just previously had the base assemblies mounted thereon. The lower ends of each of the levers 226 is formedwith a right angle extension or finger 231, the end face of which is equipped with an insert 232 composed of flexible material for engaging the contact plates 91, which operation will shortly be described. The upper ends of each of the levers 226 is provided with a comparatively short inwardly extending arm 233, the arms upon one pair of levers overlapping the ends of the arms upon the oppositely disposed pair of levers. The four arms 233 at their point of overlap, which is in line with the vertical axis of the ram 113, are spaced in close formation laterally whereby the lower end surface of an enlargement formed on the ram may simultaneously engage all arms. Coiled tension springs 234 having their ends secured to the oppositely disposed levers 226 of each pair serve to normally rock the levers inwardly to carry the flexible inserts 232 into d engagement with the contact plates91 with suflieient pressure to spread the adhesive and press them iirmly against bulbs. The aram 113 in timed relation with respect t'o the movement of the rams 114 and 115 moves downwardly to engage the arms 233 and thereby rocks the levers 226'outwardly against the action of the springs 234 and retracts the inserts 232 from the contacty platesV 91, a movement upwardly. of the ram it will be evident permits the springs to draw the inserts toward each other and into operative engagement with another set of contact plates moved into position bythe carrier 30. The period during which the inserts 232 are in engagement with the contact plates 91 occurs during the period in which the contact spreading lingers 195 and the ram 114'a're functioning to transfer base assemblies from the level of the tracks 160 to the bulbs 81, as hereinbefore described,

and consequentlythe guards 229y occupy the position shown in Fig. 11, they being carried by one of the levers 226.

Mechanism for pressing lie base assembly longitudinally upon the bnl?) y Upon abraelet 237 fixed to the frame 48 adjacent its upper surface and upon its left hand side is pivotally mounted a lever 238 for actuating a mechanism 36 for pressing the base assembly longitudinally upon the bulb, the'lever being bifurcated at its right end (Fig, 4). A pin239 extending forward from the upper end of the ram 113 operatively engages within the bifurcated end of the lever 238, the opposite end of the lever being provided with an aperture through which freely extends a rod 240. A pin 241 passing through the rod 240 above the upper face of the lever 238 provides means whereby the rod will be lifted upwardly upon a clockwise movement of the lever, caused, it will be apparent, by a downward movement of the ram 113. An arm 244 integral with the bracket 238 provides a journal or guide for the vertically reciprocal rod 240. Referring to Fig. 6, upon the lower end of the rod 240 is mounted a shoe 245 of such a length that it spans two lamp assemblies. In the operation of the apparatus and in timed relation to the movement of the carrier the lever 238 is rocked away from the pin 241 carried by the rod 240 which permits the shoe to move downwardly by the force of gravity into engagement with the upper surface of the base membersof the lamp assemblies positioned thereunder, added pressure being given to the shoes by a collar. 246 of suitable weight fixed to the rod 240. As hereinbefore described the presser wheel 31 insures that the bulbs 81 will be positioned at the bottom of the containers 80 and with the pressure of the shoe 245 the lower end surfaces of the contact plates 91 will be moved into engagement with the top surface of the containers 80, thus insuring that the over-all length of the lamps will be uniform, it being understood that the applied adhesive at this stage in the assembly of the lamp parts is still in a plastic state.

Drying onen An oven 37, Figs. 1 and 2, for drying the adhesive comprises a rectangular shaped housing positioned at the left of the frame j for furnishing suiiicient heat therein to thoroughly dry the adhesive and thereby at tachthe lamp base assemblies 94 securely to the bulbs 81 during their circuitous travel therethrough, which will be presently de As shown in dotted outline (Fig. 7v

scribed. 1) at each corner of the housing upon a frame 251 (Fig. 2) is journaled a pair of vertical shafts 252 and 253, all of the shafts' being `freely rotatable upon the frame except the pair at the lower left corner of the houslng (Fig. 1), which are driven 1n a manner 'to be presently described. Each of the shafts 252 and 253 supports a plurality of the sprocket wheels 254 around which the carrier or sprocket chain 30 is wrapped, the

sprocket Wheelsbeing solarranged that as the chain is propelled one link at a time intermittently, it ascends from' the outer sety of shafts 252 from the bottom 'to the top of the oven, each convolution ofthe chain ascending a sufficient distance to leave space for the lamps mounted on the convolution of the chain `immediately therebelow. The chain upon reaching the top of therovenv travels to the sprocket wheels 253 mountedV hereinbefore referred to and which will now be described. Positioned within the housingr ofthe oven 37 adjacent the upper end of the frame 251 (Figs. 1, 2 and 16)l is a wind motor 88 comprising two opposed air pistons 256 carried in cylinders 257 and 258,l thel pistons being integral with a common pise ton rod 259. Formed upon therod 259`is.

a `rack 260 in mesh withv ai gear wheel-261 which upon receivingmotion from' the right piston 257 (Fig. 16) transmits a counterclockwise rotary movementto ashaft' 263 journaled upon the frame' 251 through a usual pawl and ratchetmechanism 264 op-vr eratively associated With the wheel 261 and'v shaft, respectively. Upon a movement of the left piston 258 toward theright it will be apparent thatthegear Wheel 261l will idly rotate on the shaft 263 in a` clockwise direction, the pawl attachedto the 'gearidly riding over the ratchet teeth. Thus the shaft4 263 Vis rotated a predetermined'amount for each reciprocation'of the windmotor 88,

which movement is transmitted to the inner shaft 253 positionedy at the llower left corner y connected by separate pipes 269 to the cylin-` ders 257 and 258 as indicatedn in Figs. 2 and I tionedk at theyle'ft ofthe ejecting mechanism'` 39 and arranged immediately above the of the oven 37, as viewedin Fig..l 1, by a= sprocket wheel 265`attachedto the upper end of each of the shafts l263and 253 and an interconnecting` chain266. Air is admitted tol the ycylinders 257 and 258at predetermined" uniform intervals by an ordinary fourway i valve 267 (Fig. 3), theinlet 'port ofvwhich is connectedby a pipe 268 to ya vsupply of Oppositely compressed air (not shown). disposed outletports of the valve ,267 are 16. A fourth port .of thefvalve is connected by a pipe 270 to a vpoint 273 l (Fig.` 1) posi-r empty containers 80 of the carrier 30 for di# recting an intermittentV blast ',of'air into theV .containers to remove any particles of dried adhesive or other'y matter which may be p0- siticned therein;v An ,upwardly extending stem 274 of thevalve 267lc'a'rries a sprocket wli'eel 275 which is operatively connected to a sprocket Wheel'27 6 fined tothe constantly drZ-)ivenshaft` byfan interconnecting chainv The admission'of air to the right cylinder 257, which as hereinbefore. described, transmits vmotion to the outer shaft 253 positioned atl the lower'left corner of thefoven 37, as viewed inFig. 1, is timed in` such a manner that 1t occurs slightly subsequent to the in-l termittent movement of n the sprocket lwheeel .76. As a result of this previous actuation of the sprocket wheel 76 slackness is formed vin the carrier chain 30 between the idler wheel 84 andthe sprocket wheel254 (Figs.

' 1 and 2) which the chain iirst engages within'y the oven 37 as indicatedin dotted lines aty This slackness in the chain 278 (Fig. 3). n 30' occurs before the thrust of the piston 256 of they cylinder 257 occurs,` thereby preventing any deleterious strain being imparted to the chain due to the unrestrained move?" ment Vof the piston upon air being admitted to the cylinder which would tend to move the chain 30V at a greaterspeed than the'move-V ment of th'egsprocket wheel 76 permits. To support'and'guidethe chain 30' at this point there is provided a pivotal arm 281 supporting a sprocket wheel 282,` the armbeingfreely mounted' upon the stud carrying" the adjacentV idlersprocket wheel 84 (Fig.y 3),

the chain being'guidedv between the sprocket f Wheels 282 and 84. The full line position of thearm 281 and the sprocketwheel 282 indicates the normal position thereof during 'the interval in which thecarrier 30 is not traveling." Upon 'the'sprocket wheel Y76 be-y ing indexed by the Genevamovement plate 73 the arm 281 is rocked counterclockwise to the dotted line position thereof (Fig. :3), which 'movement isr assisted by ya vcoiled' spring 283 under ltension at this time and having one end fixed tothe Varm 281` and nits opposite endk to va stationary pin (not shown) Yfixed to the frame 45.

Anotherattendant positionedy as indicated by a broken line circle 328 rotates the bulbs 81 Withinv the containers 8O so as to rarrangea lpair of leading in Wires 329r (one of Which is shown in Fig. V18) extending upwardly from opposite sides ofthe bulb so that they Willbe directed toward opposite sides of the. carrier.30.` The wires 329 in ythe 'completed assembly of the lamp form an electrical path for current supplied to the plates 91 to light the filament carried inthe' bulb, the plates' engaging the bulb from opposite sides of the carrier as hereinbefore described in detail'. As the carrier l3K() travels intermittentlyin the ydirection indicated 'by the arrows V(Fig.

Vl), ythe bulbs Slmove first under the grav ity actuated pressing Wheel 31, which serves tomove them dovvn tothe bottom ofthe containersy 80 in case they rk'are not so posi'-A tioned by the attendant.f i'l`hence successively a pair of bulbs` are stopped between the adhesive applying fingersy 135 which are operated as hereinbefore describedto restricted areas ,of hot plastic adhesive rupon opposite sides of theY bulbs.
